PASADENA, Calif. (NASA PR) — The team controlling NASA’s Mars 2020 Perseverance rover has received telemetry (detailed spacecraft data) down from the spacecraft and has also been able to send commands up to the spacecraft, according to Matt Wallace, the mission’s deputy project manager. The team, based at NASA’s Jet Propulsion Laboratory in Southern California, has confirmed that the spacecraft is healthy and on its way to Mars.
NASA’s program to upgrade its 1980’s vintage ground-based tracking network is making progress after years of delay and budget overruns, although challenges remain, according to a new assessment from the Government Accountability Office (GAO).
The antenna enhancements will improve future spacecraft communications, but during the upgrades, Voyager 2 will not be able to receive new commands from Earth.
PASADENA, Calif. (NASA PR) — Starting in early March, NASA’s Voyager 2 will quietly coast through interstellar space without receiving commands from Earth. That’s because the Voyager’s primary means of communication, the Deep Space Network’s 70-meter-wide (230-feet-wide) radio antenna in Canberra, Australia, will be undergoing critical upgrades for about 11 months. During this time, the Voyager team will still be able to receive science data from Voyager 2 on its mission to explore the outermost edge of the Sun’s domain and beyond.
FORT IRWIN, Calif. (NASA PR) — Surrounded by California desert, NASA officials broke ground Tuesday, Feb. 11, on a new antenna for communicating with the agency’s farthest-flung robotic spacecraft. Part of the Deep Space Network (DSN), the 112-foot-wide (34-meter-wide) antenna dish being built represents a future in which more missions will require advanced technology, such as lasers capable of transmitting vast amounts of data from astronauts on the Martian surface. As part of its Artemis program NASA will send the first woman and next man to the Moon by 2024, applying lessons learned there to send astronauts to Mars.
NASA Planetary Science Division Director Jim Green said on Tuesday that SpaceX plans to launch two Red Dragon missions to Mars during the 2020 launch window.
“Every 26 months, the highway to Mars opens up, and that highway is going to be packed. We start out at the top of that opportunity with a SpaceX launch of Red Dragon. That will be followed at the end of that opportunity with another Red Dragon. Those have been announced by SpaceX,” Green said during an appearance at the Humans to Mars Summit in Washington, DC.
The Red Dragon is a modified version of the Dragon spacecraft SpaceX uses to deliver supplies to the International Space Station. SpaceX will send these automated vehicles to the surface as a precursor to human missions it wants to fly in the 2020’s.
SpaceX has announced that it will send a Red Dragon to the surface in 2020. However, Elon Musk’s company has said nothing publicly about a second spacecraft. Red Dragons are designed to perform automated descent, entry and landings on the martian surface.
SpaceX had planned to launch the first Red Dragon mission in 2018. However, the effort was pushed back two years due to the company’s other commitments, which include commercial cargo and crew missions for NASA and a backed up launch manifest caused, in part, by two Falcon 9 failures.
The inaugural flight test of the Falcon Heavy booster that will launch the Red Dragon spacecraft has also been delayed for more than four years. That test is currently scheduled for the third quarter of 2017.
NASA is providing about $30 million in in-kind support for the first Red Dragon flight in exchange for entry data. The space agency’s support includes trajectory analysis and tracking and communications via the Deep Space Network.
