Russian Rockets No Longer an Option

Northrop Grumman is switching from Russian-made rocket engines to U.S.-made rocket engines for its Antares rocket ships that bring supplies to the U.S. International Space Station (ISS). Russia has not shipped any engines since March following its invasion of Ukraine, so Northrop Grumman needs an alternative. It can fly two more missions with the Russian-made rockets in its inventory.

Firefly Aerospace in Texas will be able to meet these needs. In a press release, Northrop Grumman stated:

Firefly’s propulsion technology utilizes the same propellants as the current Antares rocket, which minimizes launch site upgrades. The Antares 330 will utilize seven of Firefly’s Miranda engines and leverage its composites technology for the first stage structures and tanks, while Northrop Grumman provides its proven avionics and software, upper-stage structures and Castor 30XL motor, as well as proven vehicle integration and launch pad operations. This new stage will also significantly increase Antares mass to orbit capability.

Fortunately, we have some redundancy in ISS cargo missions, with SpaceX able to pick up slack as necessary. In fact, Northrop Grumman will be contracting with SpaceX to handle three of its missions as it prepares for the new Antares system for mid-to-late 2024.

Space Mission: A Trip to the Oort Cloud?

While NASA does not have any plans to send a specific missions to study the Oort Cloud, the most distant region in our solar system containing trillions of frozen objects, it has already sent five spacecraft in that direction. Two Voyager spacecraft, two Pioneer spacecraft, and the New Horizons spacecraft are all heading that way, but it is quite a distant.

For example, the Voyager spacecraft will not hit the Oort Cloud for another 300 years and will continue to travel through the cloud for another 30,000 years before escaping the solar system. As a result, all of these spacecraft will be dead as a rock before ever hitting that region and of no use to anyone back here, yet they will still carry messages from all of us to the stars. So in that sense, they still have a mission to perform should anyone be out there.

The Oort Cloud is still a theory since it has not been observed, but there is plenty evidence regarding its existence, including the comets that come into the center of our solar system from that region. The cloud itself is believed to be a sphere rather than on the same plane as the planets, so it forms a protective ring around the planets potentially becoming a hazard to any incoming or outgoing spacecraft. What this will mean for interstellar space travel, should that day come, is anyone’s guess at this point.

Space Quote: Finally Seeing the Individual Leaves

“It is like humanity just got a brand-new pair of eyeglasses for the distant universe…We are suddenly seeing that those green areas on the tops of trees are actually made of thousands of individual leaves. We suspected it, but we are now seeing it for the first time.”

-Statement by planetary astromomer Heidi Hammel in a Washington Post article, “The Webb telescope is astonishing. But the universe is even more so.”

A Day in Astronomy: Curiosity Rover Arrives on Mars

On this day in 2012, the Mars rover Curiosity landed on Mars (using Eastern Time). The rover was sent to the Red Planet to to explore the Gale crater and look for evidence that Mars had the conditions needed to support microscopic life in its past. A video from NASA walks you through the rover’s exploration to date and also highlights Maggie, Curiosity’s duplicate here on Earth.

An anniversary posting from NASA explains more about the mission, including issues with the rover’s drilling arm, wheels, and power supply. Life on Mars can be tough.

That said, the rover has already learned a lot after 10 years and it is expected to continue exploring in the years to come. NASA noted:

…most important, Curiosity has determined that liquid water as well as the chemical building blocks and nutrients needed for supporting life were present for at least tens of millions of years in Gale Crater. The crater once held a lake, the size of which waxed and waned over time. Each layer higher up on Mount Sharp serves as a record of a more recent era of Mars’ environment.

You may have visited the Smithsonian National Air and Space Museum or ventured down to Florida to visit the Kennedy Space Center, but have you heard of the Cosmosphere in Kansas?

Started in 1962, the Cosmosphere in Hutchinson, Kansas claims to host “…the largest combined collection of U.S. and Russian space artifacts in the world and telling the comprehensive story of mankind’s race to space unlike anywhere else on Earth.”

For example, here are a few of the items you can view at the museum:

  • Flown Liberty Bell 7 Mercury spacecraft;
  • Flown Gemini X spacecraft;
  • Flown unmanned Russian Vostok;
  • Flown Apollo 13 command module, Odyssey;
  • Apollo space suits; and
  • Russian Sokul Spacesuit.

You can also find material related to German V-1 and V-2 rockets, Cold War spying, X-planes, and more. The expanded multinational coverage of space and conflict makes this a unique destination.
