Norway irked over Swedish rocket crash on its turf

April 25, 2023

The Norwegian foreign ministry expressed irritation Tuesday with
Sweden for not immediately informing it of a research rocket that
crashed in Norway, in a rare spat between the two neighbours.

The rocket, which was launched early Monday from the Esrange
Space Centre in Kiruna, northern Sweden, plunged into a
mountainside in the Malselv municipality in Norway's far north,
about 10 kilometres (six miles) from the closest inhabited area.

No one was injured and no material damage was reported.

"The crash of a rocket like this is a very serious incident that
can cause serious damage," the foreign ministry in Oslo said.

"When such a border violation occurs, it is crucial that those
responsible immediately inform the relevant Norwegian authorities
through the proper channels," it said.

The rocket was carrying out experiments in zero gravity at an
altitude of 250 kilometres.

"The rocket took a slightly longer and more westerly trajectory
than calculated and landed after a completed flight 15 kilometres
(9.3 miles) into Norway," the Swedish Space Corporation said in a
statement on Monday.

"Work on retrieving the payload is underway," it added.

Norway's foreign ministry also noted that retrieval work was not
supposed to begin without Norwegian authorisation, which had not
been granted.

Norway's Civil Aviation Authority said it had learned of the
crash from the Swedish Space Corporation's press release issued
on Monday.

From New Atlas:

This strange blue asteroid has another big surprise for us

By Bronwyn Thompson
April 26, 2023

This space-rock oddity has long puzzled scientists for its rather
non-asteroid-like behaviors, and it's just revealed yet another
curious characteristic.

In 2009, NASA's Solar Terrestrial Relations Observatory (STEREO)
craft identified that asteroid 3200 Phaethon was doing something
peculiar in orbit, brightening and growing a substantial tail as
it reached its closest point to the Sun on its 524-day orbit.

This was already a strange occurrence, since comets have tails,
due to their icy make-up, not rock-and-metal asteroids. It's long
been thought to be dust that had been expelled from the
asteroid's surface.

Now, scientists have discovered that there's no dust in sight; it
is, in fact, an impressive tail made up of sodium gas.

"Our analysis shows that Phaethon's comet-like activity cannot be
explained by any kind of dust," said lead author Qicheng Zhang,
PhD student at the California Institute of Technology. "Comets
often glow brilliantly by sodium emission when very near the Sun,
so we suspected sodium could likewise serve a key role in
Phaethon's brightening."

An earlier study had landed on sodium being the cause of
'fizzing' on the asteroid's surface. When it's close to the Sun,
Phaethon -- which is nearly 3.9 miles (6.3 km) in diameter -- has
a surface temperature of around 1,390 F (750 C), which
vaporizes certain substances.

The discovery was made with the use of two NASA solar
observatories. The Solar and Heliospheric Observatory (SOHO)
spacecraft was employed to observe the asteroid through two
filters, which could identify sodium and dust, respectively. The
researchers then hit the archives of STEREO and SOHO imaging and
found the occurrence of Phaethon's tail on 18 solar approaches
between 1997 and 2022.

The SOHO filters confirmed suspicions: the asteroid's tail was
obvious and bright when using the sodium-detecting lens, and
scientists could see how it changed shape and intensity as it
moved along its path. No evidence of dust was observed with the
other filter.

"Not only do we have a really cool result that kind of upends 14
years of thinking about a well-scrutinized object, but we also
did this using data from two heliophysics spacecraft -- SOHO and
STEREO -- that were not at all intended to study phenomena like
this," said team member Karl Battams of the Naval Research

The discovery adds to the mystery of Phaethon, which orbits
closer to the Sun than any other other named asteroid, is one of
the few to appear blue on the surface and is the source of the
annual Geminid meteor shower. Comets are generally responsible
for meteor showers.

In 2017, Phaethon -- identified in 1983 and named after the son
of the Sun god Helios in Greek mythology -- whizzed past Earth,
however it was still 6.4 million miles (10.3 million km) from the
planet. It won't head back this way again until 2093.

The study was published in The Planetary Science Journal.
