DART: Watch the Asteroid Impact

The Americans and Italians are putting on a show tomorrow night. NASA’s Double Asteroid Redirection Test (DART) spacecraft is ready to strike Dimorphos, which is a moonlet to the asteroid Didymos. All of it should be captured by Italy’s Light Italian CubeSat for Imaging Asteroids (LICIACub) in addition to DART’s own camera called the Didymos Reconnaissance and Asteroid Camera for Optical navigation (DRACO). Are you overwhelmed with acronyms yet?

The mission is a practice run on diverting an asteroid. While we are not threatened by this pair of asteroids, we may be threatened by others in the future, so what we learn here is critical.

You can view the impact later tomorrow via this NASA site starting at 6pm ET (the collision is expected at 7:14pm ET).

Extra: Here is another DART site to watch from The Johns Hopkins University Applied Physics Laboratory.

Update: The mission was a success. The video showing the DART spacecraft approaching the dirty potato called Dimorphos was impressive. The actual moonlet shown below is considerably different than the smooth asteroid in the artist’s rendering above.

Artemis I Launch Set for September 27th

This time of year the weather tends to be troublesome in the Florida region, but NASA still hopes to try again with its Artemis I uncrewed launch to the Moon on September 27th.

Here are the updated mission facts:

  • Launch date: Sept. 27, 2022
  • Mission duration: 38 days, 23 hours, 49 minutes
  • Total distance traveled: 1.3 million miles
  • Re-entry speed: 24,500 mph (Mach 32)
  • Splashdown: Nov. 05, 2022

CNN reports that “Concerns over the weather system forming in the Caribbean put the weather conditions at only 20% favorable for a launch.” So don’t get your hopes too high, but at least NASA has resolved the hydrogen leak.

Fingers crossed.

Update: You can uncross those fingers. The launch is being delayed due to weather.

Pic of the Week: Interacting Galaxy Pair

This week’s image comes again from the Hubble Space Telescope, which is keeping us entertained as the James Webb Space Telescope cycles through its required observations and spins off images from time to time.

While an earlier image appeared to show colliding galaxies, though it was believed to be an optical illusion, the collision above is real. Below is more on the image from the European Space Agency’s (ESA) Hubble site:

Galaxies can merge, collide, or brush past one another — each of which has a significant impact on their shapes and structures. As common as these interactions are thought to be in the Universe, it is rare to capture an image of two galaxies interacting in such a visibly dynamic way. This image, from the NASA/ESA Hubble Space Telescope, feels incredibly three-dimensional for a piece of deep-space imagery. 

The subject of this image is named Arp 282, an interacting galaxy pair that is composed of the Seyfert galaxy NGC 169 (bottom) and the galaxy IC 1559 (top). If you’re interested in learning more about Seyfert galaxies, you can read about the Seyfert galaxy NGC 5728 here. Interestingly, both of the galaxies comprising Arp 282 have monumentally energetic cores, known as active galactic nuclei (AGN), although it is difficult to tell that from this image. This is actually rather fortunate, because if the full emission of two AGNs was visible in this image, then it would probably obscure the beautifully detailed tidal interactions occurring between NGC 169 and IC 1559. Tidal forces occur when an object’s gravity causes another object to distort or stretch. The direction of the tidal forces will be away from the lower-mass object and towards the higher mass object. When two galaxies interact, gas, dust and even entire solar systems will be drawn away from one galaxy towards the other by these tidal forces. This process can actually be seen in action in this image — delicate streams of matter have formed, visibly linking the two galaxies.

Soyuz Launch to Space Station a Success

Earlier today, the Russian Soyuz MS-22 rocket launched from Kazakhstan and successfully placed three new inhabitants on the International Space Station (ISS): NASA astronaut Frank Rubio and Russian cosmonauts Sergey Prokopyev and Dmitri Petelin. The three will stay on the ISS for the next six month, while three cosmonauts will be returning to Earth next week after completing their own six month tours.

Even with all of the Russian posturing back on the surface, it is great to see the ISS team is remaining above the fray. That is, if you ignore the flag-waving antics of the three returning cosmonauts. Sorry, I could not leave it alone.

More Space Travel Offers from China and NASA

The China Global Television Network recently reported that China is looking into offering space rides to commercial passengers by 2025, including suborbital flights, cargo flights, and trips to Chinese Space Station. For instance, suborbital flights are expected to be priced at 2 and 3 million yuan (or $287,200 to $430,800).

Given the growing U.S. space industry with its own range of space flight options, it was only a matter of time that China would enter this commercial space race. Russia has been in the game the longest, having sold seats to U.S. astronauts hoping to reach the International Space Station (ISS) following the demise of the space shuttle.

Not to be outdone, NASA has also announced plans to take commercial passengers to the ISS at $55 million per seat. According to Tech Times, NASA is seeking commercial partners for two such flights per year starting as early as 2023. We have already discussed the Axiom Mission 1 (or AX-1 mission) to the ISS earlier this year at about the same price, so this is not a new idea. I guess the Axiom Mission 1 went well enough for NASA to see this as a regular operation.

A variety of space travel options from a variety of countries and commercial suppliers shows that playing in space can be both fun and profitable. Just ask Captain Kirk.

That is fine, as long as the tourists do not get in the way of the real work that is being conducted. With the taxpayers still footing most of the space-faring bill, we do not want space travel to be seen as only a luxury for the wealthy (similar to electric vehicles in the U.S., up to now). Space and related space travel should be seen as something belonging to everyone.
