New paper day! In 'Near-future rocket launches could slow ozone recovery', we show that scaling up use of launch vehicles 🚀 has a point where the healing of the ozone layer is affected 🧪🛰️

Layoff notices at JPL are going out today.

About 11% of the Lab, or 550 people, are being let go.

I'm thinking of my friends and colleagues there, some of whom will still be employed after today and some of whom won't.

I'm sorry you're having to deal with this.

Gibson et al. “TESS Discovers a Second System of Transiting Exocomets in the Extreme
Debris Disk of RZ Psc”
showing 24 exocomet transits and the existence of a broken power law for the sizes of these exocomets, unlike Beta Pic’s exocomet distribution #exoplanet #astrodon #astrosci
TESS light curve of RZ Psc, showing several dog tooth-like dips indicating exocomet transits. Plot os radius of exocomet versus cumulative number count - the RZ Psc shows a distinct change in slope at 2.5km, whilst the Beta Pic distribution from des Etangs shows a single straight power law.

NZ's govt has announced reforms to science funding

just one line about basic science in there: "Discovery-led science & research will continue to be funded. This will sit outside the pillars & is essential for maintaining vibrant curiosity-driven science system"

yea mate seems like a real priority
A new strategy for the science system | Ministry of Business, Innovation & Employment
The Government is changing how science, innovation and technology are funded and supported in New Zealand. The goal is a simpler and more strategic system that helps researchers turn ideas into solutions that benefit New Zealand.

It is also far from Earth, on the other side of the Sun. For all these reasons, we don’t expect to receive Juice’s observations of 3I/ATLAS until February 2026. It is a long wait indeed, but it's a big space out there. 8/8

Given Juice is still close to the Sun, it's using its main high-gain antenna as a heat shield. It will be sending data back to Earth using its smaller medium-gain antenna. 7/8

4️⃣ Unplanned scientific opportunity ahead ☄️

Beginning of November, Juice will attempt to observe comet #3I/Atlas over a period of four weeks. The team plans on using several instruments, including cameras, spectrometers and a particle sensor. 6/8

So many great ways to observe the interstellar comet. It's tricky to see in this movie, but it's there. As the comet gets closer to the Sun, PUNCH, a solar corona imager, will make daily observations. As the PUNCH data pipeline gets better (it's a new mission) this data will improve. 🧪 #planetsci

While 3I Atlas is getting to harder to see from Earth, heliospheric images in space are still tracking. Here is a movie from PUNCH tracking it yesterday (8-October).

Fair. I just saw the people's names and went 'oh, good panel'. My bad

There's a lot to be said for having the mission team able to talk about their own data ☄️

First images of comet #3I/ATLAS from Europe's Mars orbiters 😍

Observing the comet from 30 million km away, #ExoMars reveals the halo of gas and dust surrounding the comet's nucleus.

BEHOLD the majesty of the Kiwi cheese scone. This scone isn't here for a fancy tea. This scone has come to rumble. This scone demands MORE butter. This scone has OPINIONS about jam. This scone is three square meals and elevenses. This scone has HEFT.
You do not eat this scone. You experience it.
You're looking at a large yellow gold beast, AKA a kiwi cheese scone, sitting on a white stoneware plate. It dominates the plate and the small bowl featuring two hefty triangles of butter next to it. If you were to lift this scone, you would feel its heft. This scone sees cheese and says give me more! You know that if you tapped the top of this scone it would make an ominous hollow sound that, if you know your cheese scones, promises a delicious crunchy top with a soft interior. Also on this table, admiring this scone is a yellow tea cup sitting on a blue saucer. A frankly inferior looking stainless steel teapot and milk jug containing just enough brew to wash down the scone. Elsewhere on the table is a comedic book from 1936 about Gardening and my notebook that I was using to jot spotted notes. It's brown covered and nondescript, unlike the scone of might. Which is easy to descript. It is majestic.

We tried in 2019 and got called 'cavemen'. There is only so much time and 3I doesn't observe itself

Just going to say that it is hurtful when a systematic study effort by the global small-body community, with many of the campaigns led by women, with results being pushed to free open-source arXiv & data repos for scicomm as quickly as possible, is described as lacking coordination/communication

I would anticipate something more official from ESA instruments in the near future. Be very surprised if anything is out yet though, downlink was barely finished

So today I celebrate the work of @carersinstemm.bsky.social who are calling for systemic changes to funding, policy & culture to support carers in STEM. Funders & employers must listen if they recognise and value the importance of a diverse workforce.👩‍🔬🧪

Read their report 👉 carersinstemm.co.uk 8/9🧵
A Carers Guide for Institutions
1
Ensure institutional expense policy allows for the reimbursement of care-related costs including dependant and co-carer travel expenses.
2
Update and align institutional financial reimbursement policy with funder T&C’s relating to care-giving costs.
3
Establish institutional policy and disseminate to line managers and expense approvers to avoid inconsistent implementation and support.
4
Provide flexible carers grants for all staff and students with minimal administrative burden to flexibly support ad-hoc care and do not mandate online attendance.
5
Consider the competing demands of meeting sustainability goals and the requirement to support carers (e.g. trains, flight times on weekends).
6
Decouple measures of research impact and esteem from travel opportunities with updated academic guidance.
7
Allow for family-friendly travel accommodation options including booking outside of approved institutional travel providers.
8
Provide a per-diem (a daily allowance) option for complex trips to reduce
administrative burden on carers.
9
When hosting an event, ensure risk assessments and insurance policy align to allow access to those under the age of 18.
