白宫拟砍半NASA科学预算 火星采样及新望远镜项目面临断供
据彭博社披露，特朗普政府2026财年预算提案拟将NASA科学部门经费从73亿美元削减至39亿美元，降幅达46%。地球科学任务预算缩水超50%，天体物理部门骤减近70%，南希·格雷斯·罗曼太空望远镜（原计划研究星系演化）或被取消。现有哈勃与詹姆斯·韦伯望远镜维持运转，但火星样本返回任务（MSR）资金未获保障。NASA发言人证实已启动预算审议程序，但未透露具体分配细节。此次削减若生效，将重创行星科学、天体物理及地球观测领域研究，影响深空探测战略布局。

Some messages aren’t supposed to last forever. There are some Telegram groups and conversations where it’s best if messages are automatically deleted in a day or a week. Here’s how to auto-delete messages in any Telegram chat. You can enable the auto-delete feature on a per-chat basis. It works for both one-on-one conversations and group chats. Previously, you needed to use the Secret Chat feature to automatically delete messages after a set time. At the time of writing, you can choose to automatically delete messages after a day or a week. Telegram starts the timer once they are sent, not after they are read. This won’t affect the messages that were sent before enabling the feature.
The seemingly negative pandemic effects and resource/product shortages are encouraging and allowing organizations to innovate and change.The news of cash-rich organizations getting ready for the post-Covid growth economy is a sign of more than capital spending plans. Cash provides a cushion for risk-taking and a tool for growth.
