MAUVE Launched!

Posted in Maynooth, The Universe and Stuff with tags , , , , on November 28, 2025 by telescoper

After a false start a couple of days ago, the satellite MAUVE was launched at (10.44 Pacific Time (18.44 GMT) today from Vandenberg Space Force Base in California on a SpaceX Falcon-9 Transporter-15. So far, about 40 minutes after liftoff, it’s looking good.

You can see the live feed here:

As far as I know the launch went perfectly, but I’m waiting for confirmation of payload deployment, which begins about an hour after launch. The vehicle is carrying 140 different satellites, of which MAUVE (“Mission to Analyze the UltraViolet universE”) is just one.

The following is taken from my previous post. I repeat it here for completeness.

I’m not personally involved in MAUVE but the Department of Physics at Maynooth University is, through my colleague Dr Emma Whelan (who sent the above pictures) and her group. You can read more about the science – related to star and planet formation – it will do in a nice piece by Emma on RTÉ Brainstorm.

MAUVE Postponed

I was hoping to do a post this evening about the satellite MAUVE which was due to be launched at 18.18 GMT from Vandenberg Space Force Base in California on a SpaceX Falcon-9 Transporter-15. Unfortunately the launched was scrubbed with about 15 minutes to go. In fact it was originally scheduled for 11th November but was postponed then. It’s now supposed to be launched on Friday 28th November. Let’s hope it’s third time lucky!

MAUVE is a small satellite, which is to be launched with a number of others; the name stands for “Mission to Analyze the UltraViolet universE” and the heart of it is a 60cm ultraviolet telescope.

I’m not personally involved in MAUVE but the Department of Physics at Maynooth University is, through my colleague Dr Emma Whelan (who sent the above pictures) and her group. You can read more about the science – related to star and planet formation – it will do in a nice piece by Emma on RTÉ Brainstorm.

There’s a more technical description of MAUVE on the arXiv here. The abstract reads:

We present the mission concept “Mission to Analyze the UltraViolet universE” (MAUVE), a wide-field spectrometer and imager conceived during the inaugural NASA Astrophysics Mission Design School. MAUVE responds to the 2023 Announcement of Opportunity for Probe-class missions, with a budget cap of $1 billion, and would hypothetically launch in 2031. However, the formulation of MAUVE was an educational exercise and the mission is not being developed further. The Principal Investigator-led science of MAUVE aligns with the priorities outlined in the 2020 Astrophysics Decadal Survey, enabling new characterizations of exoplanet atmospheres, the early-time light curves of some of the universe’s most explosive transients, and the poorly-understood extragalactic background light. Because the Principal Investigator science occupies 30% of the observing time available during the mission’s 5 yr lifespan, we provide an observing plan that would allow for 70% of the observing time to be used for General Observer programs, with community-solicited proposals. The onboard detector (THISTLE) claims significant heritage from the Space Telescope Imaging Spectrograph on Hubble, but extends its wavelength range down to the extreme UV. We note that MAUVE would be the first satellite in decades with the ability to access this regime of the electromagnetic spectrum. MAUVE has a field of view of 900″ x 900″ a photometric sensitivity extending to mUV ≤ 24 , and a resolving power of R ~ 1000. This paper provides full science and mission traceability matrices for this concept, and also outlines cost and scheduling timelines aimed at enabling a within-budget mission and an on-time launch.

Anyway, I hope to be able to give an update on Friday evening about the successful launch of MAUVE. Fingers crossed!

Guest Post: The Euclid Consortium has an EDI challenge if ESA goes ahead with SpaceX

Posted in Euclid, LGBTQ+, The Universe and Stuff with tags , , , on September 1, 2022 by telescoper

The following is a guest post from Arthur Loureiro who is Euclid Science Ground Segment Senior Scientist at the The University of Edinburgh. Opinions expressed here are personal and do not reflect those of the Euclid Collaboration nor the University of Edinburgh.

This guest post is based on an open letter sent by Arthur Loureiro & Gabriele Mainetti to the Euclid Consortium Diversity Committee.

–o–

According to news outlets, the European Space Agency is considering using Elon Musk’s SpaceX to send the Euclid Space Telescope to L2. SpaceX is seen as an alternative to fill the gap left by the Soyuz spacecraft – removed by Roscosmos as a consequence of the Russian invasion of Ukraine. Russia made its first invasion of Ukraine back in 2014 and, since then, ESA had plans to use the future Ariane 6 rocket to deliver Euclid. But the plan to use Ariane 6 went to space (differently from Euclid) as Ariane Space signed their largest contract ever with… Bezos! The comic book vilan billionaire doesn’t seem to have enough rockets in his back garden. He needs to cut the queue ahead of Euclid to send more space junk low-orbit satellites for Amazon.

So, off to SpaceX we (seem to) go.

The issue is that SpaceX’s CEO is known to be a complicated figure (to say the least!). Musk has attacked multiple times subjects at the core of the Euclid Collaboration’s values. We cannot claim to care for diversity, inclusion, equality, LGBTQIA+ rights, climate change, vaccines, and democracy and close a deal with such a vile figure. Launching the Euclid telescope via SpaceX would mean dumping millions of euros in the pockets of someone who is very vocal against these values.

In case our telescope decides to hitch a $50+M hike in SpaceX’s Falcon 9, the Euclid Collaboration has an EDI challenge ahead.

Personally, as one of the few Latin Americans involved in Euclid, it feels like a slap in the face to know we will be doing business with him. Musk has zero respect for the fragile democracy we have in our southern continent. In 2020, for example, Musk said “We will coup whoever we want. Deal with it” about the coup against the elected president Evo Morales in Bolivia. For context, the coup was mainly motivated by gaining access to Bolivia’s Lithium reserve. I find this statement absurdly disturbing. Reminiscents of a (hopefully) long gone colonial epoch.

I cannot speak for the group, but I suspect the feeling must be similar for the LGBTQIA+ community within Euclid. Musk has consistently and openly attacked the LGBTQIA+ community on multiple fronts. For the (few) women in the Collaboration, I imagine the feeling is of absolute repulse and disgust. On top of other issues Musk has with women, the telescope they have been working for will be (possibly) launched by SpaceX where recent accusations of sexual harassment have been raised against the CEO.

As a collective and diverse group of scientists, engineers, and academics, are we endorsing Musk and his attitudes by signing a multi-million dollar contract with his company?

As a collaboration that endorses the values of EDI, science, and democracy, what are we going to do to mitigate the damage caused by paying this person and company so much money?

How are we going to deal with the bitter taste (to say the least) left for those members of the EC that has been directly or indirectly attacked by Musk and his followers?

Euclid must fly to its final destination at L2. We cannot wait to see all that our Dark Universe mission has to reveal to us! If ESA decides to use Musk’s SpaceX, that is beyond the Euclid Collaboration’s decision power. However, the Collaboration can and must discuss how to avoid being linked in any way, shape or form to this despicable figure before we change from ESA’s Euclid Mission to Elon’s Euclid Mission. Credit to Musk must be avoided at all costs as the cost will be Euclid’s shot at being a diverse and inclusive Collaboration.
