** ISS Live video stream – IBM/ISS HD Earth Viewing Experiment

Currently, live views from the ISS are streaming from an external camera mounted on the ISS module called Node 2. Node 2 is located on the forward part of the ISS. The camera is looking forward at an angle so that the International Docking Adapter 2 (IDA2) is visible. If the Node 2 camera is not available due to operational considerations for a longer period of time, a continuous loop of recorded HDEV imagery will be displayed. The loop will have “Previously Recorded” on the image to distinguish it from the live stream from the Node 2 camera. After HDEV stopped sending any data on July 18, 2019, it was declared, on August 22, 2019, to have reached its end of life. Thank You to all who shared in experiencing and using the HDEV views of Earth from the ISS to make HDEV so much more than a Technology Demonstration Payload!

Commercial activity and opportunity in cislunar space – a report & podcast

The Cislunar Market Opportunities Report: In-Space Business within the Earth-Moon System was  recently released by NewSpace Global. I was the primary analyst on the report, which surveys a wide array of commercial activities and opportunities within  cislunar space, i.e. the region from low Earth orbit to the Moon, including the lunar surface.

The particular focus of the report is on those commercial sectors that support activities in space rather than those that deliver services to earth. In-space businesses include, for example, satellite servicing and space tugs in earth orbit and communications and navigation satellites around the Moon. Such endeavors constitute an in-space infrastructure that is forming and expanding before our eyes.

The Cislunar Market Opportunities Report: In-Space Business within the Earth-Moon System

I’ve followed commercial space development closely since the 1990s yet even I’m quite surprised by the current boom in cislunar endeavors. I initially planned just a brief update on a cislunar report I wrote in 2019  but soon realized that there had been major progress since then. Rather than just concepts and plans, in almost every sector there are companies with hardware already in space or with hardware in preparation for upcoming missions to space. It took 161 pages to describe the full scope of what is happening.

I discussed the report on the  Space Economy podcast with Marc Boucher, who is the President and COO of Multiverse Media Group LLC, which now owns NewSpace Global. (Dylan Taylor is the founder and chairman of Multiverse.) Check out our discussion: Insight Into the Cislunar Market Opportunities Report – SpaceQ

When we were finalizing the report, a big challenge was deciding when to stop incorporating the seemingly continuous in-flow of news and announcements of cislunar developments. Here is a sampling of cislunar in-space business news since the report was published:

Night sky highlights for December 2022

** What’s Up: December 2022 Skywatching Tips from NASANASA JPL

What are some skywatching highlights in December 2022?
The Moon sweeps past Jupiter twice this month, and actually covers Mars completely, in an event called an occultation, on Dec. 7. The event is visible across the U.S., except for the Southeast and East Coast, where the Moon will graze closely past Mars. And throughout the month, you can find Pegasus, the winged stallion, high overhead in the south.

Stellaris: People of the Stars

ESO: Distant black hole swallowing a star discovered in visible light

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

Most distant detection of a black hole swallowing a star

This artist’s impression illustrates how it might look when a star approaches too close to a black hole, where the star is squeezed by the intense gravitational pull of the black hole. Some of the star’s material gets pulled in and swirls around the black hole forming the disc that can be seen in this image. In rare cases, such as this one, jets of matter and radiation are shot out from the poles of the black hole. In the case of the AT2022cmc event, evidence of the jets was detected by various telescopes including the VLT, which determined this was the most distant example of such an event.

Earlier this year, the European Southern Observatory’s Very Large Telescope (ESO’s VLT) was alerted after an unusual source of visible light had been detected by a survey telescope. The VLT, together with other telescopes, was swiftly repositioned towards the source: a supermassive black hole in a distant galaxy that had devoured a star, expelling the leftovers in a jet. The VLT determined it to be the furthest example of such an event to have ever been observed. Because the jet is pointing almost towards us, this is also the first time it has been discovered with visible light, providing a new way of detecting these extreme events.

Stars that wander too close to a black hole are ripped apart by the incredible tidal forces of the black hole in what is known as a tidal disruption event (TDE). Approximately 1% of these cause jets of plasma and radiation to be ejected from the poles of the rotating black hole. In 1971, the black hole pioneer John Wheeler[1] introduced the concept of jetted-TDEs as “a tube of toothpaste gripped tight about its middle,” causing the system to “squirt matter out of both ends.

We have only seen a handful of these jetted-TDEs and they remain very exotic and poorly understood events,”

says Nial Tanvir from the University of Leicester in the UK, who led the observations to determine the object’s distance with the VLT. Astronomers are thus constantly hunting for these extreme events to understand how the jets are actually created and why such a small fraction of TDEs produce them.

As part of this quest many telescopes, including the Zwicky Transient Facility (ZTF) in the US, repeatedly survey the sky for signs of short-lived, often extreme, events that could then be studied in much greater detail by telescopes such as ESO’s VLT in Chile.

We developed an open-source data pipeline to store and mine important information from the ZTF survey and alert us about atypical events in real time,”

explains Igor Andreoni, an astronomer at the University of Maryland in the US who co-led the paper published today in Nature together with Michael Coughlin from the University of Minnesota.

In February of this year the ZTF detected a new source of visible light. The event, named AT2022cmc, was reminiscent of a gamma ray burst — the most powerful source of light in the Universe. The prospect of witnessing this rare phenomenon prompted astronomers to trigger several telescopes from across the globe to observe the mystery source in more detail. This included ESO’s VLT, which quickly observed this new event with the X-shooter instrument. The VLT data placed the source at an unprecedented distance for these events: the light produced from AT2022cmc began its journey when the universe was about one third of its current age.

A wide variety of light, from high energy gamma rays to radio waves, was collected by 21 telescopes around the world. The team compared these data with different kinds of known events, from collapsing stars to kilonovae. But the only scenario that matched the data was a rare jetted-TDE pointing towards us. Giorgos Leloudas, an astronomer at DTU Space in Denmark and co-author of this study, explains that

because the relativistic jet is pointing at us, it makes the event much brighter than it would otherwise appear, and visible over a broader span of the electromagnetic spectrum.

The VLT distance measurement found AT2022cmc to be the most distant TDE to have ever been discovered, but this is not the only record-breaking aspect of this object.

Until now, the small number of jetted-TDEs that are known were initially detected using high energy gamma-ray and X-ray telescopes, but this was the first discovery of one during an optical survey,”

says Daniel Perley, an astronomer at Liverpool John Moores University in the UK and co-author of the study. This demonstrates a new way of detecting jetted-TDEs, allowing further study of these rare events and probing of the extreme environments surrounding black holes.
