The payloads were integrated into the Nanoracks BlackBox, a locker-sized platform with mechanical mounting points and electrical connections for power, data, and communication capabilities. Payloads are fully integrated into BlackBox on the ground; when they reach ISS, the astronauts aboard integrate them into ISS experiment racks, then simply leave them alone — the boxes are completely self-contained and remotely commanded via Nanoracks from the ground. This system allows for larger and more complex research payloads on the ISS, as the astronauts aren’t required to come near any potentially hazardous materials and don’t need any special expertise to run the experiments.
Four of the payloads involved technology and scientific projects. The fifth, called Sojourner 2020, contains a group of
artworks, the first-ever international “open call” art payload to the ISS, selected by SEI’s arts curator Xin Liu. Sojourner 2020 features a three-layer telescoping structure. Each layer of the structure rotates independently; the top layer remains still in weightlessness, while the middle and bottom layers spin at different speeds to produce centripetal accelerations that mimic lunar gravity and Martian gravity, respectively. Nine artists contributed works in a variety of different media, including carved stone sculpture, liquid pigment experiments, and sculptures made of transgender hormone replacement meds. Sojourner 2020 highlights the ways in which the arts can contribute to new means of encountering space; by including projects from indigenous peoples and gender minorities, the project additionally emphasizes key values of human dignity, equality, and democratizing access.
Sojourner 2020 (a 1.5U size unit, 100mm x 100mm x 152.4mm ) will be launched into low Earth orbit for about 30 days. It features a three-layer telescoping structure which creates three different “gravities”: zero gravity, lunar gravity, and Martian gravity. Each layer of the structure rotates independently. The top layer remains still in weightlessness, while the middle and bottom layers spin at different speeds to produce centripetal accelerations that mimic lunar gravity and Martian gravity, respectively. Each layer carries 6 pockets that can hold projects.
Each pocket is a container with 10mm in diameter and 12mm in depth. Though the space is limited, the artist groups proposed and accomplished artworks in a variety of different mediums, including carved stone sculpture by Erin Genia, liquid pigment experiments by Andrea Ling and Levi Cai, sculptures made of transgender hormone replacement meds by Adriana Knouf, among the others.
With space transport costs dropping, more an more artists can use space for acts of self-expression:
Sojourner 2020 highlights the ways in which the arts can contribute to new means of encountering space. While access to space is becoming more possible due to commercial launch providers, those sending projects often remain scientific or engineering researchers. Sojourner 2020 broadens this to include an unprecedented collection of international artists, thereby both democratizing access to space as well as opening space exploration to transdisciplinary perspectives. By including projects from indigenous peoples and gender minorities, the project additionally enacts key values of human dignity and equality.

** Starship prototype SN3 collapses near end of pressure testing of propellant tanks. Rather than an explosive rupture as in previous tank failures, the center tank just crumpled and collapsed. Apparently, the weight of the liquid nitrogen in the upper tank overcame the structural integrity of the middle tank. This could have happened if the middle tank was de-pressurized prematurely. This is the sort of mistake Elon Musk was referring to in a Tweeter posting after the failure in which he said, “this may have been a test configuration mistake.”
Virgin Orbit, the California-based small satellite launch company, has announced a new partnership with Oita Prefecture to bring horizontal launch to Japan. With the support of regional partners ANA Holdings Inc. and the Space Port Japan Association, Virgin Orbit has identified Oita Airport as its preferred pilot launch site — yet another addition to the company’s growing global network of horizontal launch sites — in pursuit of a mission to space from Japan as early as 2022.
Virgin Orbit and Oita Prefecture have agreed to commence a joint technical study to facilitate development of the future spaceport.
Oita Prefecture is widely recognized in Japan as not only a top-ranked tourist destination, but also as a hub for numerous high-tech ecosystems, including the steel, petrochemical, semiconductor, and automobile industries. The Oita Prefectural Government now has ambitions to extend that leadership into the space domain.

Sierra Nevada Corporation (SNC), the global aerospace and national security leader owned by Eren and Fatih Ozmen, reached a major milestone in the advancement of hypersonic propulsion with its patented VORTEX engine, advancing to the next phase of the Defense Advanced Research Projects Agency’s (DARPA) Operational Fires (OpFires) program.
Through OpFires, SNC is extending its hybrid VORTEX engine capabilities to advanced, deep throttling, restartable propulsion systems. The system utilizes benign solid fuel with a liquid oxidizer, both of which are storable on Earth and in space. Recent testing shows positive results in being able to package significant energy into a small volume that will have the ability for deep throttling and smooth restart capabilities on command. “The VORTEX flows integrated into the hybrid significantly improves performance of the hybrid engine” said Dr. Marty Chiaverini, director of Propulsion Systems at SNC.
“This program opens up a new market for SNC for preplanned or on-demand propulsion control capabilities that are applicable to both military and beyond Earth orbit propulsion capabilities,” said Tom Crabb, vice president of SNC’s Propulsion & Environmental Systems business unit. “Deep throttling and restart capabilities expand the tools for smart and unpredictable trajectories for various vehicles and systems.”
The first two phases of DARPA’s OpFires program focus on the propulsion technologies required to deliver diverse payloads to a variety of ranges. Since Phase 1 contract award, SNC has made critical discoveries in advanced rocket motor technology for the OpFires upper stage, completing more than 30 motor trials from subscale through full size. SNC hopes to demonstrate these engines in flight and offer the engines to new, promising vehicle systems.
In addition to the deep throttling, restartable, storable system for DARPA, SNC is expanding its propulsion capabilities and products with near-term flight for its Dream Chaser® spaceplane Reaction Control System, maturation of upper stage engines and development of other liquid storable engines for spacecraft, lunar, and other exploration and protection applications. SNC is also co-investing with the U.S. Air Force (USAF) for development of the engine for USAF needs. For more information, visit www.sncorp.com.

A souped-up version of the Israeli Beresheet moon lander built in Texas could be ready to carry NASA science and technology payloads to the lunar surface before the end of 2022, according to officials from Firefly Aerospace.
Firefly’s Genesis lander is one of several major projects being developed by the company headquartered just north of Austin, Texas.
The company is also developing the Alpha small satellite launcher, and a bigger rocket named Beta is on the drawing board.
Officials hope to learn this month whether NASA will sign Firefly to deliver experiments to the moon.
Filled with more than 4,000 pounds of valuable scientific experiments and other cargo, a SpaceX Dragon resupply spacecraft is set to leave the International Space Station Monday, April 6. NASA Television and the agency’s website will broadcast its departure live beginning at 9:30 a.m. EDT.
Robotic flight controllers at mission control in Houston will issue commands at 9:52 a.m. to release Dragon using the station’s Canadarm2 robotic arm. Expedition 62 Flight Engineer Drew Morgan of NASA will back up the ground controllers and monitor Dragon’s systems as it departs the orbital laboratory.
Dragon will fire its thrusters to move a safe distance from the station, then execute a deorbit burn as it heads for a parachute-assisted splashdown around 3:40 p.m. in the Pacific Ocean, southwest of Long Beach, California. The splashdown will not air on NASA TV.
Dragon launched on the SpaceX Falcon 9 rocket March 6 from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida and arrived at the space station three days later.

Following in the footsteps of the late Mk1 vehicle, SpaceX’s latest Starship prototype has been outfitted with several Tesla battery packs and motors over the last few weeks.
CEO Elon Musk has confirmed in the past that SpaceX intends to try to use Tesla batteries to power Starship rockets and Tesla motors to drive the ships’ large aerodynamic control surfaces. By all appearances, a Tesla Model S motor’s appearance on the exterior of a Starship prototype recently moved to the launch pad is a first for SpaceX. However, in 2019, SpaceX at one point planned to use and even installed battery packs on Starship Mk1 components before the ship was prematurely destroyed during testing. The nosecone those battery packs were installed in still sits in the middle of SpaceX’s growing Boca Chica rocket factory.
For Starship SN3, the purpose of its ~200 kWh of battery power is rather self-explanatory. The purpose of the Tesla Model S motor recently installed on its side is much less clear.
