The private-public partnership with NASA and Redwire will demonstrate the ability of a small spacecraft – OSAM-2 (On-Orbit Servicing, Manufacturing and Assembly) – to manufacture and assemble spacecraft components in low-Earth orbit.

The inflatable antenna technology concept was originally called the Large Balloon Reflector (LBR) concept when it was picked up by the NASA Innovative Advanced Concepts (NIAC) program in 2013. It may have sounded like a wild idea to some at first, but because NASA gave it a chance this technology could revolutionize high-speed communications. NASA 360 takes a look at a NASA Innovative Advanced Concept (NIAC) that launched a business, became a space mission, and could change the way we communicate on Earth.

NASA’s Psyche mission is preparing for a 1.5 billion-mile (2.4 billion-kilometer) solar-powered trip to the metal-rich asteroid of the same name.
In a cleanroom at NASA’s Jet Propulsion Laboratory in February 2022, twin solar arrays were attached to the spacecraft body, unfolded lengthwise, and then re-stowed as tests on Psyche continue. The five-panel, cross-shaped solar arrays are the largest ever installed on a spacecraft at JPL, so engineers had to test them one at a time.
Psyche is expected to launch no earlier than August 2022. About an hour after launch, the arrays will deploy and latch into place in a sequential process that will take 7 ½ minutes per array. They will then provide power for the journey to Psyche and for operating the three science instruments. In total, the solar arrays are 37 feet (11.3 meters) long. Only the three center panels can be deployed at JPL; the two cross panels on each wing are deployed using specialized equipment at Maxar Technologies in Palo Alto, California, where the arrays and spacecraft chassis were built. When they deploy fully in flight, the spacecraft will be about the size of a singles tennis court.
Psyche is scheduled to arrive at the asteroid in 2026 and spend nearly two years making increasingly close orbits. Scientists think the asteroid Psyche could be part of the core of a planetesimal, the building block of an early rocky planet, which would provide a unique opportunity to study how planets like our own Earth formed.

The SpaceX South Texas launch site, referred to by SpaceX as Starbase, and also known as the Boca Chica launch site, is a private rocket production facility, test site, and spaceport constructed by SpaceX, located at Boca Chica approximately 32 km (20 mi) east of Brownsville, Texas, on the US Gulf Coast. When conceptualized, its stated purpose was “to provide SpaceX an exclusive launch site that would allow the company to accommodate its launch manifest and meet tight launch windows.” The launch site was originally intended to support launches of the Falcon 9 and Falcon Heavy launch vehicles as well as “a variety of reusable suborbital launch vehicles”, but in early 2018, SpaceX announced a change of plans, stating that the launch site would be used exclusively for SpaceX’s next-generation launch vehicle, Starship. Between 2018 and 2020, the site added significant rocket production and test capacity. SpaceX CEO Elon Musk indicated in 2014 that he expected “commercial astronauts, private astronauts, to be departing from South Texas,” and he foresaw launching spacecraft to Mars from the site.
Between 2012 and 2014, SpaceX considered seven potential locations around the United States for the new commercial launch facility. Generally, for orbital launches an ideal site would have an easterly water overflight path for safety and be located as close to the equator as possible in order to take advantage of the Earth’s rotational speed. For much of this period, a parcel of land adjacent to Boca Chica Beach near Brownsville, Texas, was the leading candidate location, during an extended period while the US Federal Aviation Administration (FAA) conducted an extensive environmental assessment on the use of the Texas location as a launch site. Also during this period, SpaceX began acquiring land in the area, purchasing approximately 41 acres (170,000 m2) and leasing 57 acres (230,000 m2) by July 2014. SpaceX announced in August 2014, that they had selected the location near Brownsville as the location for the new non-governmental launch site, after the final environmental assessment completed and environmental agreements were in place by July 2014. An orbital launch of the Starship would make it SpaceX’s fourth active launch facility, following three launch locations that are leased from the US government.
SpaceX conducted a groundbreaking ceremony on the new launch facility in September 2014, and soil preparation began in October 2015. The first tracking antenna was installed in August 2016, and the first propellant tank arrived in July 2018. In late 2018, construction ramped up considerably, and the site saw the fabrication of the first 9 m-diameter (30 ft) prototype test vehicle, Starhopper, which was tested and flown March–August 2019. Through 2021, additional prototype flight vehicles are being built at the facility for higher-altitude tests. By March 2020, there were over 500 people employed at the facility, with most of the work force involved in 24/7 production operations for the third-generation SpaceX launch vehicle, Starship.

On Wednesday, May 5, Starship serial number 15 (SN15) successfully completed SpaceX’s fifth high-altitude flight test of a Starship prototype from Starbase in Texas. SN15 ascended, transitioned propellant, and reoriented itself for reentry and a controlled aerodynamic descent. The Raptor engines reignited to perform the landing flip maneuver before touching down for a nominal landing on the pad.
These Starship test flights improve our understanding and development of a fully reusable transportation system designed to carry crew and cargo on long-duration interplanetary flights, help humanity return to the Moon, and travel to Mars and beyond.

The SpaceX team attempted a high-altitude flight test of Starship serial number 15 (SN15) – our fifth high-altitude flight test of a Starship prototype from Starbase in Texas. SN15 has vehicle improvements across structures, avionics and software, and the engines that will allow more speed and efficiency throughout production and flight: specifically, a new enhanced avionics suite, updated propellant architecture in the aft skirt, and a new Raptor engine design and configuration.
Similar to previous high-altitude flight tests of Starship, SN15 is powered through ascent by three Raptor engines, each shutting down in sequence prior to the vehicle reaching apogee – approximately 10 km in altitude. SN15 performed a propellant transition to the internal header tanks, which hold landing propellant, before reorienting itself for reentry and a controlled aerodynamic descent.
The Starship prototype descended under active aerodynamic control, accomplished by independent movement of two forward and two aft flaps on the vehicle. All four flaps are actuated by an onboard flight computer to control Starship’s attitude during flight and enable precise landing at the intended location. SN15’s Raptor engines then reignited as the vehicle attempted a landing flip maneuver immediately before touching down on the landing pad adjacent to the launch mount.
A controlled aerodynamic descent with body flaps and vertical landing capability, combined with in-space refilling, are critical to landing Starship at destinations across the solar system where prepared surfaces or runways do not exist, and returning to Earth. This capability will enable a fully reusable transportation system designed to carry both crew and cargo on long-duration, interplanetary flights and help humanity return to the Moon, and travel to Mars and beyond.
