US-made lunar mission experiences 'anomaly' after separation from launch rocket

The Peregrine lander and the Vulcan rocket are both made by private companiies.


THE US-MADE PRIVATE lunar mission which blasted off from Florida this morning has encountered an “anomaly” which its operators are currently responding to. 

The problem has occurred after the Pergrine lunar lander seperated from the rocket that lifted into orbit this morning. 

A brand new rocket, United Launch Alliance’s Vulcan Centaur, lifted off from Cape Canaveral Space Force Station in Florida at 2:18 am (07:18 irish time) for its maiden voyage, carrying Astrobotic’s Peregrine lunar lander.

The launch to orbit proceeded as planned but the issue has now arrisen as Astrobotic’s Peregrine lunar lander begin its six-week voyage to the moon, the first lunar mission by an Americdan spacecraft in over 50 years. 

In an update this afternoon, Astrobotic said that the issue has prevented the lander from “achieving a stable sun-pointing orientation” :

After successfully separating from United Launce Alliance’s Vulcan rocket, Astrobotic’s Peregrine lunar lander began receiving telemetry via the NASA Deep Space Network. Astrobotic-built avionics systems, including the primary command and data handling unit, as well as the thermal, propulsion, and power controllers, all powered on and performed as expected.After successful propulsion systems activation, Peregrine entered a fully operational state. Unfortunately, an anomaly occurred, which prevented Astrobotic from achieving a stable sun-pointing orientation. The team is responding in real time as the situation unfolds and will be providing updates as data is obtained and analyzed.

‘Spot on’

The issue arose following a launch that was described as “spot on” by Eric Monda, ULA’s strategic planning director. 

“It was so cool. I ran outside to watch the launch,” he said on NASA’s live stream.

If all goes to plan, Peregrine will touch down on a mid-latitude region of the Moon called Sinus Viscositatis, or Bay of Stickiness, on 23 February .

“Leading America back to the surface of the Moon for the first time since Apollo is a momentous honor,” Astrobotic’s CEO John Thornton said ahead of the launch.

Until now, a soft landing on Earth’s nearest celestial neighbor has only been accomplished by a handful of national space agencies: the Soviet Union was first, in 1966, followed by the United States, which is still the only country to put people on the Moon.

China has successfully landed three times over the past decade, while India was the most recent to achieve the feat on its second attempt, last year.

Now, the United States is turning to the commercial sector to stimulate a broader lunar economy and ship its own hardware at a fraction of the cost, under the Commercial Lunar Payload Services (CLPS) program.

A challenging task

NASA paid Astrobotic more than $100 million for the task, while another contracted company, Houston-based Intuitive Machines, is looking to launch in February and land near the south pole.

“We think that it’s going to allow… more cost effective and more rapidly accomplished trips to the lunar surface to prepare for Artemis,” said Joel Kearns, the US space agency’s deputy associate administrator for exploration.

Artemis is the NASA-led program to return astronauts to the Moon later this decade, in preparation for future missions to Mars.

Controlled touchdown on the Moon is a challenging undertaking, with roughly half of all attempts ending in failure. Absent an atmosphere that would allow the use of parachutes, a spacecraft must navigate through treacherous terrain using only its thrusters to slow descent.

Private missions by Israel and Japan, as well as a recent attempt by the Russian space agency, have all ended in failure — though the Japanese Space Agency is targeting mid-January for the touchdown of its SLIM lander launched last September.

Making matters more fraught is the fact that it is the first launch for ULA’s Vulcan, although the company claims a 100% success rate in more than 150 prior launches.

ULA’s new rocket is planned to have reusable first stage booster engines, which the company, a joint venture between Lockheed Martin and Boeing, expects will help save costs.

Science instruments, human remains

On board Peregrine is a suite of scientific instruments that will probe radiation and surface composition, helping to pave the way for the return of astronauts.

But it also contains more colorful cargo, including a shoebox-sized rover built by Carnegie Mellon University, a physical Bitcoin, and, somewhat controversially, cremated remains and DNA, including those of Star Trek creator Gene Roddenberry, legendary sci-fi author and scientist Arthur C. Clarke and a dog.

The Navajo Nation, America’s largest Indigenous tribe, has said sending this cargo to the Moon desecrates something that is sacred to their culture. Though they were granted a last-ditch meeting with White House, NASA and other officials, their objections failed to remove the cargo.

The Vulcan rocket’s upper stage, which will circle the Sun after it deploys the lander, is meanwhile carrying more late cast members of Star Trek, as well as hair samples of presidents George Washington, Dwight D. Eisenhower and John F. Kennedy.
