February 2021: Missions to Mars – Preparing for Astronauts to Land

Let’s kick it off with our personal favorite! Mars is a highly sought after destination. Scientists believe it may have once been able to support life and, with the proper technology, may be able to in the future. The hope is that one day, astronauts will be able to step foot on the Red Planet and survive there for a long time. Our president and co-founder, Abigail Harrison, hopes to be among that team!

But before humans can land on Mars, scientists need to send spacecraft. These orbiters, rovers, and helicopters analyze Mars’ conditions to figure out how astronauts will survive. This year there are three missions headed to do just that, and they are all arriving this February!

3. February 10, 2021: Mars 2020

Mars 2020 is the mission name for the duo Perseverance and Ingenuity. These are a rover and helicopter drone, respectively, launched by NASA that will land at Mars’ Jezero crater on February 18th, 2021. Scientists think the Jezero crater was once a lake, making it an important site to explore. Upon landing, this mission is set to last about 1 Mars year, which is approximately 687 Earth days.

Mars 2020: Mission

Perseverance and Ingenuity have different missions. Perseverance will study Mars’ habitability and seek out signs of past and present life. It also will collect Martian samples for a future mission that will bring said samples back to Earth. Perseverance will also work on landing techniques for future missions and study conditions on the Red Planet that affect astronaut survival. Meanwhile, Ingenuity will guide Perseverance from the sky, dodging rocky terrain and scoping out new sites. Name a more iconic duo, we’ll wait!

Mars 2020: Significance

If successful, Ingenuity will be the first powered flight on a planet beyond Earth. This means that a team at NASA’s Jet Propulsion Laboratory will be controlling Ingenuity’s movements remotely. Also, two audio microphones will be used for the first time during landing.

March 29, 2021: Boeing Starliner – Private Spaceflight on the Rise

The Boeing Company is an aerospace manufacturer that has partnered with NASA for the Commercial Crew Program. This program transports crews to and from the International Space Station in the first crewed space flights by private companies. Boeing’s Starliner is one of the crew capsules that will do this.

Boeing Starliner: Mission

Before Boeing can send crews into space, they need to conduct plenty of test flights. On March 29th, Boeing will conduct the second orbital test flight in Earth’s orbit, uncrewed. If successful, Boeing will move on to the first crewed test flight, currently scheduled to launch in the middle of this year. Then, by the end of the year, the first operational flight of Boeing Starliner will launch.

Boeing Starliner: Significance

The launches of Boeing Starliner are significant because spaceflight by privately-owned companies is so new! In the past, we have only seen SpaceX accomplish such a feat. Using privately-owned companies to launch spacecraft is exciting because it’s more affordable. We can expect various benefits to be opened as spaceflight becomes more easily accessible.

Update as of April 2021: Boeing’s second orbital test flight has been delayed to August or September 2021. Due to this, the first crewed test flight and first operational flight have been pushed back as well.


First Half of 2021: Chinese Space Station, Tianhe – Back to Space!

In the first half of this year, the first module of the new Chinese space station, Tianhe, will launch! The entire space station will be about 20% as massive as the International Space Station. China is not included in the 15-nation partnership of the International Space Station but had a prototype space station, Tiangong-1, from September 2011 to April 2018.

Tianhe: Mission

The Tianhe module will launch from the Wenchang Satellite Launch Center in Hainan, China, onboard a Long March 5th B rocket. It will be a living space for astronauts and provide needed life support. The entire construction of the space station is set to be completed by 2022.

Tianhe: Significance

This is a demonstration of the  China National Space Administration’s technologies and their ability to house astronauts in space! With their space station, CNSA astronauts will conduct scientific tests and experiments in ways they were unable to before.


DART Spacecraft

July 22, 2021: DART Mission – Asteroid Defense

The Double Asteroid Redirection Test (DART) mission is being conducted by NASA and will launch July 22nd. The DART spacecraft aims to test technologies needed for planetary defense. But don’t worry about a giant asteroid coming our way just yet! It is important to note that there is no immediate threat coming to Earth … at this time.

DART: Mission

The DART spacecraft is headed to the Didymos binary asteroid and is set to arrive in September 2022. There are two bodies of this asteroid: the primary and the moonlet. The primary is larger, roughly 780 meters across, and the moonlet is approximately 160 meters across. DART will crash into the moonlet, changing the moonlet’s speed in its orbit around the primary body. We like this solution a little more than the one in Michael Bay’s Armageddon (1998), to say the least.

DART: Significance

This mission is the first demonstration of the kinetic impactor technique. This is a  technique that aims to change the motion of an asteroid in space. If successful, this will be a useful tool in planetary defense! You only need to go to the dinosaur exhibit of any natural history museum to see why this is important!

Update as of April 2021: The DART mission launch window has been delayed to later this year. The window will open on November 24, 2021.

Fall 2021: Commercial Lunar Payload Services – Resources to the Moon

Commercial Lunar Payload Services (CLPS) is a program operated by NASA that allows American companies to send lunar payload deliveries to the Moon. (Payload is another word for cargo and is what the spacecraft will be carrying.) These payloads will bring resources, technologies, and equipment needed to future NASA Artemis missions. Beginning in 2021, NASA aims to launch two CLPS missions each year.

CLPS: Mission

The two companies that will send payloads in 2021 are Astrobotic Technology and Intuitive Machines, both launching in the fall. Astrobotic Technology has 11 payloads that it will send to a large crater on the near side of the Moon called Lacus Mortis. Intuitive Machines has five payloads it will send to Oceanus Procellarum, a dark spot on the lunar surface. Fun fact: each payload is about the size of a shoebox!

CLPS: Significance

These missions’ success will mark the first time an American robotic mission has landed on the Moon in nearly 50 years! The payloads brought to the lunar surface will help ensure the success of the future Artemis missions, which plan to send the first woman to the Moon!
