NASA Selects Blue Origin as Second Artemis Lunar Lander Provider

May 19, 2023

 

To develop a human landing system for the agency’s Artemis V mission to the Moon, NASA has selected Blue Origin of Kent, Washington. Through Artemis, NASA will explore more of the Moon than ever before, uncovering more scientific discoveries, and preparing for future astronaut missions to Mars.

 

Blue Origin will design, develop, test, and verify its Blue Moon lander to meet NASA’s human landing system requirements for recurring astronaut expeditions to the lunar surface, including docking with Gateway, a space station where crew transfer in lunar orbit. In addition to design and development work, the contract includes one uncrewed demonstration mission to the lunar surface before a crewed demo on the Artemis V mission in 2029. The total award value of the firm-fixed price contract is $3.4 billion.

 

“Today we are excited to announce Blue Origin will build a human landing system as NASA’s second provider to deliver Artemis astronauts to the lunar surface,” said NASA Administrator Bill Nelson. “We are in a golden age of human spaceflight, which is made possible by NASA’s commercial and international partnerships. Together, we are making an investment in the infrastructure that will pave the way to land the first astronauts on Mars.”

 

For the Artemis V mission, NASA’s SLS (Space Launch System) rocket will launch four astronauts to lunar orbit aboard the Orion spacecraft. Once Orion docks with Gateway, two astronauts will transfer to Blue Origin’s human landing system for about a weeklong trip to the Moon’s South Pole region where they will conduct science and exploration activities. Artemis V is at the intersection of demonstrating NASA’s initial lunar exploration capabilities and establishing the foundational systems to support recurring complex missions in lunar orbit and on the surface as part of the agency’s Moon to Mars exploration approach.

 

Adding another human landing system partner to NASA’s Artemis program will increase competition, reduce costs to taxpayers, support a regular cadence of lunar landings, further invest in the lunar economy, and help NASA achieve its goals on and around the Moon in preparation for future astronaut missions to Mars.

 

The agency previously contracted SpaceX to demonstrate an initial human landing system for the Artemis III mission. Under that contract, the agency also directed SpaceX to evolve its design to meet the agency’s requirements for sustainable exploration and to demonstrate the lander on Artemis IV. As a result of the contract with Blue Origin to demonstrate on Artemis V a lander that meets these same sustainable lander requirements, including capabilities for increased crew size, longer mission duration, and delivery of more mass to the Moon, multiple providers will be available to compete for future opportunities to fulfill NASA’s lunar surface access needs for Artemis missions.

 

By supporting industry’s development of innovative human landing system concepts and designs, NASA will help increase access to space for the benefit of all.

 

“Having two distinct lunar lander designs, with different approaches to how they meet NASA's mission needs, provides more robustness and ensures a regular cadence of Moon landings,” said Lisa Watson-Morgan, manager, Human Landing System Program at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “This competitive approach drives innovation, brings down costs, and invests in commercial capabilities to grow the business opportunities that can serve other customers and foster a lunar economy.”

Hubble Peers into a Glistening Star Cluster

May 19, 2023

 

The densely packed globular cluster NGC 6325 glistens in this image from the NASA/ESA Hubble Space Telescope. This concentrated group of stars lies around 26,000 light-years from Earth in the constellation Ophiuchus.

 

Globular clusters like NGC 6325 are tightly bound collections of stars with anywhere from tens of thousands to millions of members. They can be found in all types of galaxies and act as natural laboratories for astronomers studying star formation. This is because the constituent stars of globular clusters tend to form at roughly the same time and with similar initial composition, meaning astronomers can use them to fine-tune their theories of how stars evolve.

 

Astronomers inspected this particular cluster not to understand star formation, but to search for a hidden monster. Though it might look peaceful, astronomers suspect this cluster could contain an intermediate-mass black hole that is subtly affecting the motion of surrounding stars. Previous research found that the distribution of stars in some highly concentrated globular clusters – those with stars packed relatively tightly together – was slightly different from what astronomers expected.

 

This discrepancy suggests that at least some of these densely packed globular clusters – including perhaps NGC 6325 – could have a black hole lurking at the center. To explore this hypothesis further, astronomers turned to Hubble’s Wide Field Camera 3 to observe a larger sample of densely populated globular clusters, which included this star-studded image of NGC 6325. Additional data from Hubble’s Advanced Camera for Surveys was also incorporated into this image.
