Howdy everybody. This week we have quickly escalating area climate, simply in time for Monday’s Artemis 1 launch. We have now new knowledge from Perseverance, and the routinely record-breaking James Webb area telescope has — shock! — damaged one other file. We additionally salute the late, nice Star Trek alumna Nichelle Nichols.
Photo voltaic Climate Continues to Escalate
Yesterday afternoon, a magnetic filament on the solar let go, releasing a partial halo coronal mass ejection (CME) towards Earth. It is going to arrive Monday, however it should most likely be a glancing blow. NOAA provides a 50-50 probability that it will trigger a gentle geomagnetic storm, creating auroras across the Arctic Circle. To date, no one has forecast any threat for the Artemis launch.
As we speak’s area climate is way much less gentle, and altering quickly. Earlier this morning, SpaceWeather.com reported that “Sunspot AR3089 is crackling with a sequence of intensifying M-class photo voltaic flares. The strongest to date (Aug. 26 @ 1216 UT) registered M7 and triggered a shortwave radio blackout over a lot of Europe and Africa.” NASA’s Photo voltaic Dynamics Observatory captured one in every of these excessive UV flashes, which you’ll see right here:
We do not know but if AR3089 will include an related CME. In the meantime, the report concludes, “AR3089 seems to be on the verge of manufacturing an X-flare.” Extra will turn into clear with new knowledge from SOHO coronagraphs.
Artemis 1 Launches on Monday
The Artemis 1 launch is sort of approaching. On Monday, NASA’s long-delayed House Launch System will take off from Pad 39B on the company’s Kennedy House Heart in Florida. It is an uncrewed mission—however the rocket will nonetheless have three distinctive passengers in its Orion capsule.
We have beforehand written about two of them: two feminine model torsos named Helga and Zohar. Most crash check dummies are male-bodied, so most security gear is sized for males. Sadly, that implies that girls are disproportionately prone to be injured throughout a crash or accident. Helga and Zohar will likely be testing out security gear and a shiny new radiation safety vest, all sized for ladies. That by itself is cool sufficient. However we’re happy to report that the launch can have a 3rd passenger: a model named Commander Moonikin Campos, who will helm the mission.
The FINAL bracket for the Title the #Artemis Moonikin Problem is reside:
Delos: Nostalgic, romantic. The island the place Apollo and Artemis have been born, based on Greek delusion.
Campos: Resourceful, problem-solver. A dedication to Arturo Campos, key participant in bringing Apollo 13 house.

The model Commander’s title is a nod to intrepid NASA electrical engineer Arturo Campos, whose contingency plans helped get the Apollo 13 astronauts safely house. Aboard Orion, the model will likely be testing out the Orion Crew Survival System, the spacesuits that Artemis astronauts will put on throughout launch and touchdown.
Artemis 1 will not contact down on the moon. As an alternative, it is sure for lunar orbit, the place the Orion capsule will spend some weeks in orbit earlier than splashing down within the Pacific. NASA is streaming the launch, and the YouTube stream of Pad 39B is already reside.
Break a leg guys.
JWST Reveals Its Largest Night time Sky Picture Ever
The Cosmic Evolution Early Launch Science Survey (CEERS) has launched the biggest picture of the night time sky ever — and it is from the James Webb area telescope. Knowledge for the brand new starfield comes from Webb’s NIRCam and MIRI devices. It is a beautiful composite shot, and it is so new that scientists are nonetheless poring over it to make their experiences.
In keeping with the group, these photos cowl “near-infrared to mid-infrared wavelengths within the EGS subject — a small patch of sky close to the deal with of the Large Dipper.” The researchers have made ultra-high decision photos accessible on their Github for anybody who desires to poke round a bit. This launch, which the group is looking Epoch 1, covers lower than half of the CEERS survey’s whole survey space, so extra large-scale photos needs to be accessible sooner or later as soon as the group finishes its work.
Webb Detects Carbon Dioxide in One other Planet’s Ambiance
Talking of issues named 39B, we have written earlier than concerning the exoplanet WASP-39 b. It is a so-called “Sizzling Jupiter” — a gasoline big roughly the scale of Jupiter, that orbits very near its host star. The truth is, WASP-39 b is about 8x nearer to its star than Mercury is to the solar, and the planet’s “12 months” is simply 4 days lengthy. Sizzling Jupiters seem like pretty widespread within the universe and scientists are nonetheless unraveling why our personal photo voltaic system lacks one.
Nonetheless, the Webb Telescope could have one thing to say about this. For the primary time, the JWST has detected carbon dioxide within the environment of one other planet.
We have beforehand detected atmospheric water vapor, sodium, and potassium, however by no means picked up CO2 earlier than. So how did we do it this time? We had assist from the planet’s orbit, which is “edge-on” with respect to Earth. In a weblog put up, NASA explains: “As a result of completely different gases take in completely different mixtures of colours, researchers can analyze small variations in brightness of the transmitted mild throughout a spectrum of wavelengths to find out precisely what an environment is fabricated from.”
Perseverance Finds Extra Proof of Historical Water on Mars
NASA’s Perseverance rover and its companion area copter, Ingenuity, have been shaking off a few of the winter’s mud. This week, NASA introduced that the rover discovered that Jezero Crater’s flooring is made up of volcanic rocks which have interacted with water. Two separate scientific papers element the findings.
“One nice worth of the igneous rocks we collected is that they are going to inform us about when the lake was current in Jezero. We all know it was there extra just lately than the igneous crater flooring rocks shaped,” mentioned Perseverance venture scientist Ken Farley of Caltech, the lead writer of one of many experiences. “It will deal with some main questions: When was Mars’ local weather conducive to lakes and rivers on the planet’s floor, and when did it change to the very chilly and dry situations we see at the moment?”
To make the observations, scientists used onboard devices, together with Perseverance’s SuperCam laser and a ground-penetrating radar referred to as RIMFAX (Radar Imager for Mars’ Subsurface Experiment).
Nichelle Nichols Will Relaxation Among the many Stars
When the Vulcan Centaur rocket makes its maiden flight later this 12 months, it will be carrying some significantly valuable cargo. The rocket’s major mission is to launch Astrobotic Know-how’s Peregrine lunar lander, however it should even be carrying the stays of Star Trek star Nichelle Nichols.
On-screen, Nichols is greatest recognized for the function of Nyota Uhura on the 1966 tv sequence Star Trek. Nichols originated the half and returned to the character for Star Trek: The Animated Sequence, the six Star Trek characteristic movies, a Futurama episode, varied fan-created initiatives, and a number of other video video games over the previous 30 years.
Nichols portrayed the primary interracial kiss in US tv historical past with William Shatner. Her function as Uhura impressed Whoopi Goldberg’s portrayal of Guinan, in addition to the profession of NASA astronaut (and fellow Star Trek actor!) Mae Jemison. Following Nichols’ trailblazing custom, Jemison herself went on to be the primary Black lady in area, in addition to the primary individual to turn into each an astronaut and a Star Trek actor.
Off-screen, Nichols labored with NASA for years to recruit a various group of astronauts, together with Sally Experience and Charles Bolden. Even late in life, Nichols remained an enthusiastic advocate for area exploration and astronomy. She flew a twin science and outreach mission aboard SOFIA, NASA’s flying telescope, in 2015. And now, a part of her will relaxation eternally in starlight. Farewell to an icon.
As August attracts to an in depth, why not strive somewhat stargazing? Right now of the 12 months, the constellation Cygnus is a wonderful telescope goal. Plus, this weekend is the brand new moon. Skywatchers will not should take care of fairly as a lot moonlight.
NASA skywatching skilled Preston Dyches explains that Cygnus, the swan, flies excessive within the japanese sky after darkish. Cygnus has an total form like a T or cross, and accommodates a star sample generally referred to as “the Northern Cross.”
Cygnus is anchored by its brightest star, Deneb, which represents the swan’s tail. Good Deneb is the northernmost of the three stars within the Summer time Triangle, and it is seen even via mild air pollution. If Deneb is the tail, double star Albireo is its beak. Albireo is nice for stargazing, because it reveals lovely blue and gold colours via even probably the most modest telescope.
Cygnus lies proper alongside the airplane of the Milky Means, so it is dense with glittering stars, darkish mud clouds, plus distinctive options together with the North America Nebula, the Veil Nebula, and the Blinking Planetary Nebula.
That is all for this week, people. We’ll be watching the Artemis launch livestream proper together with you on Monday. See you quickly!
