The Indian Space Research Organisation (Isro) will launch the BlueBird Block-2 communications satellite for US company AST SpaceMobile today using its heavy-lift Launch Vehicle Mark-3 (LVM3). Weighing 6,100 kg, it will be the heaviest payload ever placed in low Earth orbit by the LVM3. The mission marks a milestone in Isro's commercial space efforts.
Satelit Van Allen Probe A milik NASA, yang diluncurkan pada 2012 untuk mempelajari sabuk radiasi Bumi, dijadwalkan memasuki kembali atmosfer awal pekan ini setelah kehabisan bahan bakar pada 2019. Badan antariksa tersebut telah menyetujui pengecualian keselamatan karena risiko pemasukan kembali melebihi standar pemerintah, meskipun kemungkinan menimbulkan korban tetap rendah yaitu 1 banding 4.200. Sebagian besar pesawat luar angkasa seberat 1.323 pon akan terbakar habis, dengan beberapa puing berpotensi mencapai permukaan.
