Nasa boss says he hopes astronauts may one day return his rover. The director of Nasa's Mars exploration programme says he hopes that one day the rover Curiosity might be brought back to Earth by astronauts.

If you mean personal income taxes, you can file them any time after January 1, and they are due on or before April 15, unless you file for an extension. In USA, you may file personal income taxes beginning January 2 and the deadline is April 15 or the first business day thereafter.
If you are unable to file your federal income tax return by the due date, you may be able to get an extension from the Internal Revenue Service (IRS). But this does not grant you more time to pay your taxes. You may be able to get an automatic six-month extension to file your return. To do so, you must file IRS Form 4868, Application for Automatic Extension of Time To File U.S. Individual Income Tax Return by the due date for filing your calendar year return (usually April 15) or fiscal year return. For a Spanish version of this form, download IRS Form 4868sp.
