NASA Sets Path to Return Mars Samples, Seeks Innovative Designs

NASA - Breaking News - Mon, 04/15/2024 - 12:52pm

NASA Administrator Bill Nelson shared on Monday the agency’s path forward on the Mars Sample Return program, including seeking innovative designs to return valuable samples from Mars to Earth. Such samples will not only help us understand the formation and evolution of our solar system but can be used to prepare for future human explorers and to aid in NASA’s search for signs of ancient life.

Over the last quarter century, NASA has engaged in a systematic effort to determine the early history of Mars and how it can help us understand the formation and evolution of habitable worlds, including Earth. As part of that effort, Mars Sample Return has been a long-term goal of international planetary exploration for the past two decades. NASA’s Perseverance rover has been collecting samples for later collection and return to Earth since it landed on Mars in 2021.

“Mars Sample Return will be one of the most complex missions NASA has ever undertaken. The bottom line is, an $11 billion budget is too expensive, and a 2040 return date is too far away,” said Nelson. “Safely landing and collecting the samples, launching a rocket with the samples off another planet – which has never been done before – and safely transporting the samples more than 33 million miles back to Earth is no small task. We need to look outside the box to find a way ahead that is both affordable and returns samples in a reasonable timeframe.” 

The agency also has released NASA’s response to a Mars Sample Return Independent Review Board report from September 2023. This includes: an updated mission design with reduced complexity; improved resiliency; risk posture; stronger accountability and coordination; and an overall budget likely in the $8 billion to $11 billion range. Given the Fiscal Year 2025 budget and anticipated budget constraints, as well as the need to maintain a balanced science portfolio, the current mission design will return samples in 2040.

To achieve the ambitious goal of returning the key samples to Earth earlier and at a lower cost, the agency is asking the NASA community to work together to develop a revised plan that leverages innovation and proven technology. Additionally, NASA soon will solicit architecture proposals from industry that could return samples in the 2030s, and lowers cost, risk, and mission complexity.

“NASA does visionary science – and returning diverse, scientifically-relevant samples from Mars is a key priority,” said Nicky Fox, associate administrator, Science Mission Directorate, at NASA Headquarters in Washington. “To organize a mission at this level of complexity, we employ decades of lessons on how to run a large mission, including incorporating the input we get from conducting independent reviews. Our next steps will position us to bring this transformational mission forward and deliver revolutionary science from Mars – providing critical new insights into the origins and evolution of Mars, our solar system, and life on Earth.”

Do black holes hide the secrets of their ancestors?

Some black holes are so massive they were likely created as smaller black holes that merged. Maybe we can use such black hole "children" to learn about the black hole "ancestors."

NASA’s LRO Observes 2024 Solar Eclipse Shadow

NASA - Breaking News - Mon, 04/15/2024 - 11:45am

Preparations for Next Moonwalk Simulations Underway (and Underwater)

As the Moon blotted out the Sun to viewers across the United States during the April 8 solar eclipse, NASA’s Lunar Reconnaissance Orbiter (LRO) captured an image from some 223,000 miles away of the highly anticipated celestial event.

This spectacular image showing the Moon’s shadow on Earth’s surface was acquired during a 20-second period starting at 2:59 p.m. EDT (18:59:19 UTC) on April 8, 2024, by NASA’s Lunar Reconnaissance Orbiter. When LRO acquired this image, the shadow of the Moon was centered near Cape Girardeau, Mo.NASA/Goddard/Arizona State University

There are three cameras that comprise the LRO camera (LROC) suite: two Narrow Angle Cameras (NAC) and one Wide Angle Camera. The Earth’s image with the shadow in it was acquired by one of the two Narrow Angle Cameras.

The LROC Narrow Angle Cameras are line scanner cameras: they only have one line of pixels, and images are built up line-by-line by the spacecraft’s motion as it orbits the Moon.

Acquiring an image of Earth requires the spacecraft to rapidly rotate to build up the image.

LRO is managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, for the Science Mission Directorate at NASA Headquarters in Washington. Launched on June 18, 2009, LRO has collected a treasure trove of data with its seven powerful instruments, making an invaluable contribution to our knowledge about the Moon. NASA is returning to the Moon with commercial and international partners to expand human presence in space and bring back new knowledge and opportunities.

NASA Selects New Crew for Next Simulated Mars Journey

NASA has selected a new crew of four volunteers to participate in a simulated mission to Mars within a habitat at the agency’s Johnson Space Center in Houston.

Jason Lee, Stephanie Navarro, Shareef Al Romaithi, and Piyumi Wijesekara will step into the agency’s Human Exploration Research Analog, or HERA, on Friday, May 10. Once inside, the team will live and work like astronauts for 45 days. The crew will exit the facility on June 24 after they “return” to Earth. Jose Baca and Brandon Kent are this mission’s alternate crew members.

HERA enables scientists to study how crew members adapt to isolation, confinement, and remote conditions before NASA sends astronauts on deep space missions to the Moon, Mars, and beyond. Crew members will carry out scientific research and operational tasks throughout their simulated mission to the Red Planet, including a “walk” on Mars’s surface using virtual reality. They will also experience increasing communication delays lasting up to five minutes each way with Mission Control Center as they “near” Mars. 

This crew is the second group of volunteers to participate in a simulated Mars mission in HERA this year. The most recent crew completed its HERA mission on March 18. Two other missions will follow this year, with the final HERA crew slated to wrap up on Dec. 20.

In a first for HERA, one crew member, Shareef Al Romaithi, hails from the United Arab Emirates (UAE) and will participate in the mission through a partnership between NASA and the UAE’s Mohammed Bin Rashid Space Centre (MBRSC).

As with the previous HERA mission this year, NASA’s Human Research Program is conducting 18 human health studies during the mission. The experiments will evaluate the physiological, behavioral, and psychological responses of crew members in an environment similar to what astronauts will face on a trip to Mars. Seven of these studies are collaborations with the MBRSC and the European Space Agency (ESA). Insights gleaned from the studies will allow researchers to develop and test strategies aimed at helping astronauts overcome obstacles on long missions deep into space.

The primary crew of the upcoming mission is:
