These huge solar arrays are set for a mammoth space voyage

NASA has shown off the massive solar arrays that will help power its Psyche spacecraft to a distant asteroid of the same name later this year.

A video (below) shared by NASA this week shows the spacecraft’s twin solar arrays opening to their full length of 37 feet (11.3 meters) during a test exercise at the space agency’s Jet Propulsion Laboratory (JPL) in California.

“Seeing the spacecraft fully assembled for the first time is a huge accomplishment; there’s a lot of pride,” said Brian Bone, who leads assembly, test, and launch operations for the mission at JPL. “This is the true fun part. You’re feeling it all come together. You feel the energy change and shift.”

Covering 800 square feet (75 square meters) — about the size of a singles tennis court — the spacecraft’s five-panel, cross-shaped solar arrays are the largest ever installed at JPL, NASA said.

During the mission, which is expected to launch from the Kennedy Space Center in August, the enormous arrays will fully deploy about an hour after lift-off, with the procedure taking just eight minutes.

With the arrays fully open, the Psyche spacecraft will take about three-and-a-half years to travel 1.5 billion miles (2.4 billion kilometers) to the metal-rich Psyche asteroid, which is 173 miles (280 kilometers) at its widest point and said by NASA to be shaped “somewhat like a potato.”

The spacecraft will spend two years studying the asteroid from a close distance in a mission that scientists hope will help answer fundamental questions about the formation of our solar system.

This year is a busy one for NASA as it oversees a number of notable missions. It recently, for example, launched a next-generation satellite for National Oceanic and Atmospheric Administration and is also gearing up for the highly anticipated Artemis I mission using its new SLS rocket to send the Orion spacecraft on a flyby of the moon.

NASA’s Mars Helicopter, Ingenuity, captured an aerial image of the Perseverance rover during its latest flight at the end of last week.

The aircraft and rover arrived together on the red planet in February 2021, and since then both have been operating inside the Jezero Crater, a dried-up lake that scientists believe could contain evidence of ancient life.

Astronauts install a fifth new solar array at the International Space Station
Astronaut Woody Hoburg watches as a new roll-out solar array deploys after he and fellow NASA spacewalker Stephen Bowen (out of frame) successfully installed it on the space station.

Two astronauts performed a spacewalk yesterday, heading outside the International Space Station (ISS) to install a new solar array as part of a long-term plan to upgrade the station's power system. NASA astronauts Steve Bowen and Woody Hoburg spent just over six hours outside the station, completing all of their objectives for the spacewalk.

Bowen and Hoburg were installing a new solar array called an IROSA (International Space Station Roll-Out Solar Array) to the station's 1A power channel. This is one of six IROSAs that are being installed on the ISS over a period of several years to modernize the arrays, which provide power to the station. Some of the old solar arrays were approaching 20 years old. They were designed for only 15 years of operation originally and upgrades began in 2021.
