The rate of descent did not slow as much as expected,
and the spacecraft probably made a hard landing.
The laser instrument that measured how high Resilience was above the surface was slow in making its measurements,
which may have contributed to the problem.
“At this point, we do not know clearly about the cause,”
Takeshi Hakamada, the chief executive of Ispace, said in translated remarks.
The loss of the second mission could lead NASA to rethink its pla…

Ispace of Japan’s Moon Lander Resilience Has Crashed
The loss of the Resilience spacecraft by Ispace repeated a crash into the moon in 2023 of the company’s first robotic lunar landing mission.

Kinetic approximation for equations of discrete turbulence in the subcritical case
We consider a damped/driven cubic NLS equation on a torus under the limit when first the amplitude of solutions goes to zero and then the period of the torus goes to infinity. We suggest another proof of the kinetic approximation for the energy spectrum under a subcritical scaling, extending to the exact solutions result obtained in [Dymov, Kuksin, Maiocchi, Vladuts '2023] for quasisolutions which were defined as the second order truncations of decompositions for the solutions in amplitude. The…

International collaboration of Ukrainian scholars: Effects of Russia's full-scale invasion of Ukraine International collaboration of Ukrainian scholars: Effects of Russia's full-scale invasion of Ukraine
This study explores the effects of Russia's full-scale invasion of Ukraine on the international collaboration of Ukrainian scholars. First and foremost, Ukrainian scholars deserve respect for continuing to publish despite life-threatening conditions, mental strain, shelling and blackouts. In 2022-2023, universities gained more from international collaboration than the NASU. The percentage of internationally co-authored articles remained unchanged for the NASU, while it increased for universitie…

Moment-sos and spectral hierarchies for polynomial optimization on the sphere and quantum de Finetti theorems
We revisit the convergence analysis of two approximation hierarchies for polynomial optimization on the unit sphere. The first one is based on the moment-sos approach and gives semidefinite bounds for which Fang and Fawzi (2021) showed an analysis in $O(1/r^2)$ for the r-th level bound, using the polynomial kernel method. The second hierarchy was recently proposed by Lovitz and Johnston (2023) and gives spectral bounds for which they show a convergence rate in $O(1/r)$, using a quantum de Finet…

The origin of the coherent radio flash potentially associated with GRB 201006A
Rowlinson et al. 2023 recently claimed the detection of a coherent radio flash 76.6 minutes after a short gamma-ray burst. They proposed that the radio emission may be associated with a long-lived neutron star engine. We show through theoretical and observational arguments that the coherent radio emission, if real and indeed associated with GRB 201006A and at the estimated redshift, is unlikely to be due to the collapse of the neutron star, ruling out a blitzar-like mechanism. Instead, we show …

Observing the spaces around me, whether it is the landscape, the built environment, or simply the places that I inhabit; finding that rare quality of beauty in the mundane and the every-day; creating memories that words cannot express.
