Rockets, Space transport roundup

Space transport roundup – Feb.6.2020

A sampling of recent articles, videos, and images dealing with space transport (find previous roundups here):

[Update 23:00 EST: The OneWeb satellites were successfully deployed into the target orbits: OneWeb successfully launches 34 more satellites into orbit | OneWeb

OneWeb, the global communications company with a mission to bring connectivity to everyone everywhere, today announced the successful launch of 34 satellites, aboard a Soyuz launch vehicle from the historic Baikonur Cosmodrome, Kazakhstan.

Lift-off occurred on February 06th at 21:42 pm UTC. The OneWeb satellites separated from the rocket and were dispensed in nine batches over a period of several hours.

This launch is the second successful launch in one of the largest civilian satellite launch campaigns in history. It will help build OneWeb’s phase one constellation of 648 satellites that will deliver high-speed, low-latency global connectivity, while addressing the world’s most pressing connectivity problems.

The communications company is on schedule to provide global coverage to customers in 2021, starting with the first commercial services in the Arctic this year. This follows OneWeb both securing global priority spectrum rights and successfully launching its first batch of satellites in 2019.

OneWeb’s network will provide a unique combination of high data throughput, low latency, true global coverage and a range of user terminals for multiple markets including maritime, aviation, government and enterprise.

Update 19:06 EST: The Soyuz launch of the OneWeb satellites reached orbit successfully this afternoon (US Eastern time). The Fregat-M upper stage is currently carrying out a series of burns that will culminate in the release of the satellites starting at around 20:30 this evening.:

Although the launch is on a Russian rocket from the famous Baikonur Cosmodrome in Kazakhstan, the launch is considered an Arianespace operation due to the collaboration with the Euro-Russian Starsem company. Starsem also launches Soyuz rockets from the Arianespace facility in Kourou, French Guiana.

More about the launch and OneWeb:

*** Transport from space to East Russia took place today as well with the return of a Soyuz capsule from the ISS with NASA astronaut Christina Koch, European astronaut Luca Parmitano, and Aleksandr Skvortsov. Koch set “a record for the longest single spaceflight in history by a woman”.

Alongside its rocket test building, Astra has been assembling a 250,000-square-foot manufacturing facility that Kemp says will be able to churn out hundreds of rockets a year. “Our strategy is to always focus on the bottom line,” he says. “Nothing is sacred. We’re able to profitably deliver payloads at $2.5 million per launch, and our intent is to continue to lower that price and increase the performance of our system.”

** Rocket Lab successfully launches first Electron mission of 2020:

In addition to the successful placement of the NRO satellite into orbit, additional progress was made towards the goal of recovering and reusing the Electron first stage:

The re-entry test for ‘Birds of a Feather’ is the second time Rocket Lab has guided an Electron first stage booster down to sea-level, following on from the first successful re-entry test conducted on the ‘Running Out of Fingers’ mission in December 2019. Once again, initial analysis shows the stage made it back to sea-level intact following a guided descent, proving that Electron can withstand the immense heat and forces generated on re-entry.

To guide the stage to a planned splashdown, Electron’s first stage was equipped with on-board guidance and navigation hardware, including S-band telemetry and onboard flight computer systems. The stage was also equipped with a reaction control system to orient the booster 180-degrees for its descent and keep it dynamically stable for the re-entry.

The fuel called “Ecosene” provides a greener alternative to kerosene. Ecosene produces up to 45% less greenhouse emissions than normal kerosene. The fuel goes through a two step process which transforms the previously landfill waste in to useable fuel to help place earth observation satellites in to orbit to monitor the United Nations sustainability development goals.

** Update on PLD Space of Spain: PLD Space books first suborbital flight, nears resolution of engine setback – SpaceNews.com

Spanish launch startup PLD Space says [it has] secured a second customer for the maiden flight of its Miura 1 reusable suborbital rocket while tackling development issues that prevented the mission from occurring last year.

Pablo Gallego Sanmiguel, PLD Space’s senior vice president of sales and customers, said Embry-Riddle Aeronautical University in Florida will fly four student- and faculty-built experiments on Muira 1. Those payloads take the remaining commercial space on the mission, which will also fly two microgravity experiments for the Bremen, Germany-based Center of Applied Space Technology and Microgravity, also known as ZARM. Half the rocket’s payload space will carry sensors to study its first flight. 

PLD Space planned to launch Miura 1 in 2019, but delayed the rocket’s debut after a “series of test firing anomalies” during engine development, Gallego Sanmiguel said by email.

The purposes of Earth’s Space Elevators are to 1) deliver cargo to the Enterprises assembling along the geosynchronous belt near the Space Elevator’s GEO Regions; and 2) support interplanetary flights from the APEX Regions; to the Moon, to Mars, and elsewhere.

Since the interplanetary flights from the Apex will use the latent ΔV, (derived from Earth’s rotation – transformed into radial speed at departure from the Apex); Space Elevators are established around the Solar System as part of the Galactic Harbour transportation network. Elevators operate near the Moon, on Mars, on key asteroids within the asteroids belt and elsewhere. We see immense cargo craft moving from Elevator to Elevator bringing supplies and equipment; and returning with raw materials for processing in one of the several GEO regions and later to Earth. This is the third dimension of trade, commerce, transportation, and humankind.

** NASA awards contract to SpaceX for launch of the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission in December 2022: NASA Awards Launch Services Contract for Earth Science Mission | NASA

NASA has selected SpaceX of Hawthorne, California, to provide launch services for the agency’s Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) mission.

The total cost for NASA to launch PACE is approximately $80.4 million, which includes the launch service and other mission related costs. The PACE mission currently is targeted to launch in December 2022 on a Falcon 9 Full Thrust rocket from Cape Canaveral Air Force Station in Florida.

The PACE mission represents the nation’s next great investment in understanding and protecting our home planet. The mission will provide global ocean color, cloud, and aerosol data that will provide unprecedented insights into oceanographic and atmospheric responses to Earth’s changing climate. PACE will help scientists investigate the diversity of organisms fueling marine food webs and the U.S. economy, and deliver advanced data products to reduce uncertainties in global climate models and improve our interdisciplinary understanding of the Earth system.

**** SpaceX releases Rideshare Payload Users Guide (pdf). The Smallsat Rideshare Program provides payload space for small satellites on Falcon 9 launches. The a primary payload, typically a batch of the company’s Starlink satellites.

The prices are exceptionally low for smallsats, e.g. $1M for a 200kg satellite to sun synchronous polar orbit. The Rideshare website provides an interactive guide to estimating the cost for a smallsat mission. Reservations can also be made online.

The goal is to provide routine access to space.The launch opportunities will take place at regular intervals:

SSO missions approximately every 4 months.

So if a payload is delayed, it can ride on a subsequent launch.

If your payload is delayed, apply 100% of monies paid toward cost of rebooking on a future mission, subject to a 10% rebooking fee.

**** Total number of Falcon 9 launches will surpass 100 by end of this year if there are no major failures: SpaceX’s workhorse Falcon 9 rocket expected to reach major launch milestone in 2020 – Teslarati

Hours after SpaceX launched its 240th new Starlink satellite into orbit, Elon Musk took to Twitter to cryptically reveal that the company’s workhorse Falcon 9 rocket could “reach triple digits this year” if everything goes according to plan.

Designed and built by SpaceX in the late 2000s, the Falcon 9 rocket launched for the first time in June 2010. Developed for the unfathomably low price of $300 million from clean-sheet design to first orbital launch, the original single-core Falcon 9 rocket – known as V1.0 – was about 48m (160 ft) tall, weighed 333 metric tons (735,000 lb) fully fueled, and was capable of launching almost 10.5 metric tons (23,000 lb) into low Earth orbit (LEO). Famously, when provided with Falcon 9’s basic specifications and characteristics, an independent NASA study estimated that the rocket’s development would have cost the agency anywhere from $1.7 billion to $4 billion to design and build.

**** Falcon 9 booster for the latest Starlink mission returns from the sea. The booster landed harder than usual but the legs absorbed the impact just fine.

Here is a view of the booster’s return from USLaunchReport:

B1051 is still in excellent shape. The landing legs did their job. Appears to be approx. 5ft lower than normal. Incredible when you think of the force the landing legs must absorb.

****** First SN-1 Starship test flight could happen in a couple of months: SpaceX requests permission to fly new Starship rocket on 12-mile-high test flight – The Verge

SpaceX is already planning the next big test flight of its future Starship rocket out of southern Texas. As early as mid-March, the company is hoping to fly a test version of the vehicle to a super high altitude and then land it upright on solid ground, proving the rocket can be reused and potentially touch down on other worlds.

The upcoming test is detailed in new paperwork SpaceX filed with the Federal Communications Commission, which provides licensing to aerospace companies that are hoping to fly their vehicles to space. Specifically, the FCC allocates which radio frequencies companies can use to communicate with their vehicles during flight.

SpaceX notes in its filing that it wants special authority to communicate with its Starship rocket while the vehicle flies to an altitude of 12.4 miles or 20 kilometers — nearly halfway to the edge of space. Starship would take off from SpaceX’s test facility at Boca Chica, Texas, and the company would attempt to land the vehicle near the launch site using the rocket’s Raptor engines. SpaceX also plans to send data of the vehicle’s trajectory to both the Air Force and NASA.

****** To achieve a SN-1 flight so soon, activities are ramping up at Boca Chica Beach. New tanks are being assembled, the stainless steel bands for the main fuselage of the SN-1 Starship are being produced and stacked, several new structures have gone up to protect manufacturing from the elements, the last of the private residents near the site are being bought out to make it less hazardous to carry out tests and launch activities, and new workers are being hired.

ESO: ALMA spots red giant engulfing companion star

The latest report from the European Southern Observatory (ESO):

ALMA catches beautiful outcome of stellar fight

This new ALMA image shows the outcome of a stellar fight: a complex and stunning gas environment surrounding the binary HD101584. The colours represent speed, going from blue — gas moving the fastest towards us — to red — gas moving the fastest away from us. Jets, almost along the line of sight, propel the material in blue and red. The stars in the binary are located at the single bright dot at the centre of the ring-like structure shown in green, which is moving with the same velocity as the system as a whole along the line of sight. Astronomers believe this ring has its origin in the material ejected as the lower mass star in the binary spiralled towards its red-giant partner. Click for larger images

Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA), in which ESO is a partner, have spotted a peculiar gas cloud that resulted from a confrontation between two stars. One star grew so large it engulfed the other which, in turn, spiralled towards its partner provoking it into shedding its outer layers.

Like humans, stars change with age and ultimately die. For the Sun and stars like it, this change will take it through a phase where, having burned all the hydrogen in its core, it swells up into a large and bright red-giant star. Eventually, the dying Sun will lose its outer layers, leaving behind its core: a hot and dense star called a white dwarf.

“The star system HD101584 is special in the sense that this ‘death process’ was terminated prematurely and dramatically as a nearby low-mass companion star was engulfed by the giant,”

said Hans Olofsson of the Chalmers University of Technology, Sweden, who led a recent study, published in Astronomy & Astrophysics, of this intriguing object.

Thanks to new observations with ALMA, complemented by data from the ESO-operated Atacama Pathfinder EXperiment (APEX), Olofsson and his team now know that what happened in the double-star system HD101584 was akin to a stellar fight. As the main star puffed up into a red giant, it grew large enough to swallow its lower-mass partner. In response, the smaller star spiralled in towards the giant’s core but didn’t collide with it. Rather, this manoeuvre triggered the larger star into an outburst, leaving its gas layers dramatically scattered and its core exposed.

The team says the complex structure of the gas in the HD101584 nebula is due to the smaller star’s spiralling towards the red giant, as well as to the jets of gas that formed in this process. As a deadly blow to the already defeated gas layers, these jets blasted through the previously ejected material, forming the rings of gas and the bright bluish and reddish blobs seen in the nebula.

A silver lining of a stellar fight is that it helps astronomers to better understand the final evolution of stars like the Sun.

“Currently, we can describe the death processes common to many Sun-like stars, but we cannot explain why or exactly how they happen. HD101584 gives us important clues to solve this puzzle since it is currently in a short transitional phase between better studied evolutionary stages. With detailed images of the environment of HD101584 we can make the connection between the giant star it was before, and the stellar remnant it will soon become,”

says co-author Sofia Ramstedt from Uppsala University, Sweden.

Co-author Elizabeth Humphreys from ESO in Chile highlighted that ALMA and APEX, located in the country’s Atacama region, were crucial to enabling the team to probe “both the physics and chemistry in action” in the gas cloud. She added:

“This stunning image of the circumstellar environment of HD101584 would not have been possible without the exquisite sensitivity and angular resolution provided by ALMA.”

While current telescopes allow astronomers to study the gas around the binary, the two stars at the centre of the complex nebula are too close together and too far away to be resolved. ESO’s Extremely Large Telescope, under construction in Chile’s Atacama Desert,

“will provide information on the ‘heart’ of the object,”

says Olofsson, allowing astronomers a closer look at the fighting pair.
